Abstract
In some implementations, a system can be configured to allow remote control devices to quietly obtain status information related to various audio/video playback devices. For example, a streaming device (e.g., a user device, phone, etc.) can establish a streaming connection to a playback device. The playback device can be configured to only accept a single streaming connection (i.e., master connection). A remote control device (e.g., a user device, phone, etc.) can quietly connect (i.e., control connection) to the playback device without interrupting the master connection to obtain status information related to the playback device and or the media being streamed to the playback device. The remote control device can provide commands through the control connection to adjust the playback of the streamed media at the playback device.
